Questions
Does Puerto Rico tap water have PFAS?
In EPA's UCMR 5 testing, 39 of 99 Puerto Rico water systems (39%) had at least one PFAS compound detected, and 28 had PFOA or PFOS above EPA's 4 ppt limit.
What is the best water filter in Puerto Rico?
It depends on your utility. Where PFAS is above EPA's limit, reverse osmosis is the most effective option. Where the main concern is lead from home plumbing or chlorine taste, a certified carbon filter is enough. Enter your address to get a match.
